Abstract
A constricting clutch brake element (10) is operative to selectively transmit mechanical power between relatively movable rotating members. A plurality of backing plates (38) releasibly engage a plurality of friction linings (34). The friction linings are selectively moved radially to operatively engage annular body (12) and a central rotating member (26). The friction linings are releasibly engaged with corresponding backing plates (38) through interengaging ear portions (52) of the lining and slots (62) of the backing plates.
Claims26
Apparatus comprising:
- a friction lining configured for removable engagement with a constricting clutch brake element,
- wherein the clutch brake element includes
- a generally annular body,
- a backing plate movably mounted in operative supported connection with the body, wherein the backing plate is movable in a radial direction relative to the body,
- wherein the friction lining includes,
- a lining plate,
- a friction pad in operative supported engagement with the lining plate, wherein the friction pad includes a wear surface, wherein the wear surface is generally opposed of an area of engagement of the friction pad and the lining plate,
- a pair of ear portions, wherein each ear portion is in operative supported connection with the lining plate and extends generally parallel of the wear surface,
- wherein each ear portion is configured to releasibly slidingly engage a corresponding slot of the backing plate, wherein each slot extends generally perpendicular of the radial direction, whereby in operatively engaged relation of the friction lining and the backing plate, the wear surface is movable relative to the annular body in the radial direction.

The apparatus according to claim 21
- wherein the lining plate includes in cross section
- a central portion, wherein the central portion underlies the friction pad at a side of the friction pad opposed of the wear surface, and
- wherein each of the ear portions extend generally parallel to and are radially and angularly offset from the central portion.
Apparatus comprising:
- a friction lining configured for removable engagement with a constricting clutch brake element, wherein the element includes
- a generally annular body,
- a backing plate movably mounted in operative supported connection with the body, wherein the backing plate is selectively movable radially relative to the body,
- wherein the friction lining includes:
- a lining plate,
- a friction pad operatively engaged with the lining plate, and
- at least one projecting portion in operative connection with the lining plate,
- wherein the at least one projecting portion is configured to releasably slidingly engage at least one corresponding slot in the backing plate to operatively engage and disengage the friction lining and the element, wherein when the backing plate and the friction lining are in an operative position the friction pad is selectively radially movable relative to the body.
5 more elements
Apparatus comprising:
- a constricting clutch brake element including:
- an annular body,
- a backing plate movably mounted in operative connection with the body, wherein the backing plate is movable along a radial direction relative to the annular body,
- an expandable tube in operative connection with the backing plate, wherein the expandable tube is operative to move the backing plate radially inward responsive to tube expansion,
- at least one friction lining, wherein the friction lining includes a friction pad in operative connection with the friction lining, wherein the friction pad is radially movable relative to the body responsive to radial movement of the backing plate,
- an interengaging projection and slot, wherein the friction lining includes one of the projection and slot and the backing plate includes the other of the projection and slot, and wherein the backing plate and the friction lining are releasibly engageable through relative movement thereof in a direction generally perpendicular of the radial direction.
